Odd and even mazes where the first digit is a trap
Walk on even numbers only, or only on odd ones. At two and three digits the numbers are picked so that judging by the first digit gets it wrong — 43 starts with a 4 and is odd — which leaves the last digit, the method being taught.
The last digit is the only one that matters.
An odd and even number maze generator, printable as a PDF. Choose even or odd, pick numbers to 20, two digits or three digits, and generate. At two and three digits most numbers have a first digit of the opposite kind — the shortcut children really use to guess, and exactly the one that fails here. There is exactly one route from the arrow to the star.
